I'll be curious to see how the diving crowd responds. I'm willing to bet it's a nice-to-have. It seems like a number of hardcore divers don't wear watches at all and are reliant upon dive computers, so I also can't help but wonder also just how important lume is?
For me it's critical. I can't imagine what life would be like if I had to actually get out from under the covers at night and roll over in bed to look at the clock just to know what time it is. I have to think that I'd be at risk of pulling a neck muscle or something.
